Iron telluride thin films made superconducting for stable qubits in quantum computer chips

https://www.eurekalert.org/news-releases/1109236

"qubits in quantum chips rely on superconducting thin films with stable crystal structure... superconductive below -263°C... iron and telluride atoms deposited onto cadmium telluride substrate using molecular beam epitaxy... 20% lattice misalignment typically leads to defects, but instead resulted in superconducting film... led to higher-order epitaxial matching (alignment) between film/ substrate reducing lattice distortion, enabling superconductivity"
